The morphology and ultrastructure of the alimentary canal in the adult female of the Japanese wax scale, Ceroplastes japonicus Green (Hemiptera: Coccoidea: Coccidae), was investigated using light microscopy, scanning electron microscopy and transmission electron microscopy. The results showed that the foregut was subdivided into a sclerotized pharynx and an oesophagus. A pair of salivary glands attached in the middle of the foregut. The loop-shaped midgut was narrow and longer than the foregut and its inner wall lined with a thick layer of epithelia. The hindgut was divided into a narrower ileum and a broader rectum, with the well-developed filter chamber enclosed in the anterior rectum. Malpighian tubules consisted of two brownish-yellow moniliform tubules with pores, approximately 1 μm in diameter, scattered on the outer surface and many spherical crystals inside the tubules.
采用光镜、扫描电镜和透射电镜技术研究了日本龟蜡蚧（Ceroplastes japonicus Green）雌成虫的消化道形态和超微结构。结果表明，前肠分为角质化的咽和食管。一对唾液腺附着在前肠中部。环形状的中肠较窄，比前肠长，其内壁衬有一层厚厚的上皮细胞。后肠分为较窄的回肠和较宽的直肠，在前直肠内有发达的过滤室。马氏管由两条带孔的黄褐色念珠状小管组成，孔的直径约为 1μm，散在小管的外表面，小管内有许多球形晶体。
